OSCAR SAYRE, OF ANGERONA, WEST-VIRGINIA..-

APPLE-CORER.

SPECIFICATION forming part of Letters Patent No. 551,099, dated December10, 1895. Application filed June 14,1894. Serial No. 514,563. (Nomodel.)

To all whom it may concern:

Be it known that I, OSCAR SAYRE, a citizen of the United States,residing at Angerona, in the county of Jackson and State of VestVirginia, have invented a new and useful Apple Corer, of which thefollowing is a specification.

My invention relates to apple-corers, and has for its object to providea simple, inexpensive, and efficient device adapted to simultaneouslycore and divide an apple, two sets of cutters being employed to providefor continuous operation, the cutters operating alternately.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of a device embodying myinvention. Fig. 2 is a vertical central section of the same. Fig. 3 is adetail view of one of the plungers. Fig. at is a detail transversesection of the operating-gear and the contiguous parts of the device toshow the means for mounting said gear. Fig. 5 is a plan view of amodified form of cutter.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates an elliptical frame spanned longitudinally by an arch 3,having vertical sides or standards 2. Arranged within the ellipticalbase or frame 1 and concentric with the foci thereof are core-knives 5,and radiating from said core knives are straight knives.

The arch is provided with a parallel-sided slot 6, in the sides of whichare formed bearings 7 and 8, the bearing 8 being larger than the bearing7 and being adapted for the reception of the hub 10 of the gear 9.Extending through the central opening of the gear and through thealigned bearing 7 in the arch is a spindle 10, to which the gear iskeyed, said spindle being provided with an operating-handle 12.

Mounted in the ends of the slot 6 are staffs 13 of plungers 16, saidplungers being adapted to force apples upon the upper sharpened edges ofthe knives, and the staffs are provided at their inner sides with racks15 for engagement, respectively, by opposite sides of the gear. Securedin the ends of the slot 6 and embracing the outer and lateral surfacesof the plunger-staffs 13 are the fixed channel-guides 14, which hold thestaffs with the racks in engagement with the teeth of the gear.

- From the above description it will be seen that the operation of theplungers is alternate,whereby an apple may be arranged upon one of thecore-cutters, while the plunger which co-operates with the othercore-cutter is in its depressed position, or as it approaches itsdepressed position, whereby the operation of the apparatus issubstantially continuous.

In order to reduce, as far as possible, the weight of the corer, thearch is made hollow, as shown in Figs. 2 and 4, and hence the use of thechannel-guides 14 provides the requisite bearing-surfaces for theplunger-staffs and strengthens the same to prevent displacement of theparts due to the lateral thrust of the gear.

In the modified form shown in Fig. 5 intermediate cutters 17 areemployed to divide the fruit into smaller pieces.

Various changes in the form, )roportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what I claim is- The herein describedapple corer, the same comprising an open elliptical base or frameprovided with core and straight cutters, an arch spanning the baselongitudinally and provided with a parallel-sided slot, verticalchannel-guides arranged at the extremities of the slot and extendingabove and below the arch, a gear mounted in bearings at the center ofthe arch and having a spindle and means connected thereto for operatingthe gear, and plungers having staffs mounted in said channel-guides andprovided at their inner sides with racks in engagement withopposit-esides of the gear, whereby reciprocatory movement in alternatedirections will be imparted to the plungers, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto alfixedmy signature in the presence of two Witnesses.

OSCAR SA'YRE. Vitnesses:

E. T. PARK, THEODORE SAYRE.
